2002 Toyota 4Runner Sport Utility
with AM/FM/CD player; with 6 speakers
Factory Stereo Installed [change]
Factory replacement info:
In-dash stereo
7-3/32" depth; Size code DD,J
Rear speakers
Rear Door: 4" factory speaker note "Your factory speaker doesn’t match any aftermarket speaker size exactly. Here, we list the largest speaker that will fit in the factory location. As you shop, we’ll show you all options for this location."
So you need to go to crutchfield.com and do some shopping on there and it will tell you what will fit. I would HIGHLY recommend them too. If you buy anything from them, they give you written guides on how to install it and if you need anything else you can call them and they walk you through it.
